Summary from user-provided translated excerpt: The supplied attachment attributes a Feb. 3, 2024 post to jibro and says it reproduces an AI DeepL translation of a Tiny Mandragore nursery listing. The excerpt reports up to −10°C at sites sheltered from icy winds, says significant damage is observed below −10°C despite higher hardiness claims, and separately says the fruit is resistant to −6°C. These are translated, second-hand nursery claims about its plant, not an independently verified trial or a measurement by the forum poster. The full thread and original nursery text were not independently retrieved. The excerpt supplies no exact site, event date, exposure duration, temperature instrument, tree age, rootstock, or quantified recovery method; preserve the stated cold-wind qualification.

USDA GRIN identifies RRUT 182 as cultivar Succari and lists Succory and Sukkari as synonyms. This supports a cultivar-name connection to the UCR source’s “Succory sweet orange” wording, but RRUT 182 is not identified as the exact pollen-source accession or tree used for US-119.

The thread shows only relative post ages, so an exact publication date is unavailable. Commenter u/Optimal_Reserve_295 describes tasting one fruit as good for a Poncirus hybrid but poor versus a Satsuma; no sample provenance, location, harvest date, or tree conditions are given. Other users make conflicting unverified taste, growth, yield, and cold claims without identified specimens. These are individual comments, not measurements or cultivar-wide results.

Post dated 19 July 2013; no explicit byline is visible. The post's prose is not tied to a documented specimen. A separate commenter reports poor fruiting and splitting, but the capture does not resolve exact commenter name/date. The detailed cultivar passage attributed to “[5]” is quoted background, not admitted here as independent evidence because the cited work was not verified.

Edition 2 identification profile; no individual author or publication day shown. Provides a taxonomic parent formula and morphology for foliage, twigs, crown, and fruit, including an unscored “taste sour” descriptor. It gives no accession-specific sample, field site, or measurement method; sensory wording is retained as a source-attributed descriptor, not scored.

eyeckr of Virginia Beach, Virginia, says their US-119 looked dead after the 2013–14 winter and separately reports that a friend’s large tree elsewhere in the city remained alive. The thread’s broader regional 5–6°F record-low context is not assigned to either tree and is not an individual minimum. No tree age, rootstock, exact site, exposure, or recovery follow-up is given.

Primary publisher abstract. Identifies US-119 and selection 17-11 as scions on Swingle citrumelo rootstock; compares them with Hamlin orange and satsuma during fall 1993–spring 1997, using leaf-disc electrolyte-leakage assessment. The abstract reports freezing tolerance similar to satsuma and says 17-11 was significantly hardier than US-119 at several study times. It gives no absolute temperature threshold, exposure duration, site, sample size, or whole-tree survival result.

Post 305 quotes J. Stewart Nagle’s Citrus for the Gulf Coast as describing US119 or “Snow Sweet” as juicy, with a moderately sweet-orange flavor and a lingering bitter trifoliate aftertaste. This is a second-hand quotation; the book edition and page are unverified, and the poster does not report tasting the fruit. The wording does not establish “Snow Sweet” as an alias.

Summary from transcript: At 3:30–4:33, the narrator identifies a US-119 in a Virginia Beach multi-graft garden, describing thick, curly leaves and occasional bifoliate leaves. He says fruit can be decent but the hard peel may split after irregular watering followed by rain; if ripened, it tastes somewhat like an unripe orange with some sweetness. One grower report; rootstock, exact sample date, maturity protocol, and tasting method are unstated.

Summary from transcript: The presenter offers a fruit as US-119 and compares its flavor to syrup and orange-flavored Pixy Sticks; captions repeatedly render the name as “US19,” so sample identity is presenter-attributed. These are subjective candy comparisons, not intensity ratings. Seed comments differ between pieces in the tasting. No sample date, maturity method, or cold exposure is established.

Summary from transcript: At 8:23–9:05, the narrator shows a US-119 graft moved from a greenhouse/garage outdoors that day and sees flowers on new growth. The narrator is unsure whether it will survive and reports hearing mixed hardiness accounts. The video does not document a winter exposure or survival result; the observation day is not stated.

Summary from transcript: In the original Italian narration, the speaker describes a potted US-119 in Northern Italy, over five years old and not very productive. He says the current February fruit is overripe and unlike his usual early-December fruit; usual fruit is sweet with no excessive acidity. He distinguishes a very bitter rind from slight bitterness in part of the late sample. Spoken fruit-size weights are rough estimates, not protocol-based measurements. The English auto-dub at https://www.youtube.com/watch?v=Nd7TO-7mIq0 is the same tasting and is not an independent sample.

Summary from transcript: The Mulberries evaluates one partly ripe US-119 fruit supplied by Ross, not fruit from the narrator’s own tree. The final source-specific scorecard totals 74/100. It reports 139 g (rounded), 10.5 °Bx, and a pH-strip reading of about 3.0; scores seediness as 9/10 (“almost seedless”), peelability 3/10, juiciness 6.5/10, zest quality 8/10, sourness/balance 7/10, bitterness 10/10 (none), sweetness 8/10, trifoliate influence 8.5/10 (low), and edibility 9/10. Flavor/aroma are described as sweet orange, pineapple, and floral. The narrator’s “highly nucellar” comment is speculative, not an embryo/genetic result; proposed Bishop Citrandarin crossing is hypothetical. Scores are source-specific, not standardized; no exact seed count or controlled-cross result is documented. English auto-generated captions were exported; the final overlaid scorecard at 28:10 was separately visually reviewed.

Publisher-indexed full text, pp. 1670–1671, reports 1973 cross T9R80 (Duncan grapefruit × an unnamed Poncirus trifoliata selection) × Succory sweet orange; US 119 was selected in 1980 from 173 seedlings. It reports that an estimated −12.2 °C 1981 freeze caused defoliation and separately states that fruiting occurred annually from 1980 onward. Small one-year-old trees in Byron, Georgia, reportedly froze back to the ground at an estimated −19.4 °C; Barrett attributes this to unpublished data. This describes top dieback, not established whole-tree death or root recovery. The article reports about 5–6 seeds per fruit and states that the seeds are 95–100% nucellar, without an assay method or sample denominator. These observations do not establish a guaranteed cultivar-wide cold threshold. The publisher-indexed full text was reviewed; the direct PDF download returned an HTML error page, so no visual PDF inspection is claimed.
